摘要:
The invention provides an inkjet method for producing a solder mask in the manufacture of a Printed Circuit Board. By using a solder mask inkjet ink containing at least one photo-initiator, at least one free radical polymerizable compound and at least one allyl sulfone compound as adhesion promoter, a high quality solder mask withstanding the high thermal stress during the soldering process while maintaining excellent physical properties, may be produced.

摘要:
A backsheet (1) for a photovoltaic module (5) comprising a support (10) and a weather resistant outerlayer provided on a side of the support characterized in that the weather resistant outerlayer comprises an at least partially cured coating from a curable composition wherein the curable composition comprises a monofunctional methacrylate and a difunctional (meth)acrylate monomer.
摘要:
A radiation curable ink containing a) a monomer including at least one vinyl ether group and at least one (meth)acrylate group; b) a monomer including a five membered cyclic anhydride; and c) an aliphatic tertiary amine. The radiation curable ink allows stable inkjet printing on solder masks exhibiting good adhesion and high scratch resistance after curing.
摘要:
A method is disclosed for the formation of a heat mode image with good differentiation between Dmin and Dmax. The method essentially comprises information-wise laser exposure of a layer pack comprising a layer containing a reducing agent, a barrier layer, and a layer containing a reducible organic metal salt, preferably silver behenate. The barrier layer is destructible by laser radiation and allows transfer of reducing agent in the exposed parts while no such transfer occurs in the unexposed parts. Preferably, an overall heat post-treatment is given. A mono-sheet and a two-sheet version of the invention are described.
